Guest guest Posted August 2, 2003 Report Share Posted August 2, 2003 You are no doubt correct "in general". Anyone eating modest amounts of processed food will get more than enough sodium. However I am aware of at least two individuals with presumably very healthful diets who were not getting adequate sodium and suffered symptoms (lethargy, malaise) which reversed as soon as they corrected the deficiency. It is human nature to look at issues through our personal filters so let me explain my personal experience and source of my bias. As a young adult eating ad-lib I saw my blood pressure creep up from 120/80 to 135/90 and suspect I was well on the road to your proposed " I'm sure that all people get hypertensive sooner or later ". I hope you are at least a little right because regular exercise brought my BP back down to below 120/80. Later losing a few tens of pounds and improving my dietary choices has dropped my BP to borderline low <100/60. I'm 54 now and wouldn't mind my BP rising some :-). Except for occasional dizziness upon standing too quickly I think I can live with the low BP, however I do add salt to some recipes and try to get daily minimum recommendations. I repeat we are all individuals and general advice is not for everyone... invest a little effort to learn what you should be doing for your personal situation.

Guest guest Posted August 3, 2003 Report Share Posted August 3, 2003 Hi , Yes, there are diseases that require or suggest that those afflicted eat sodium to control it. I recall a lady with a rare disease in one of the cr groups (I can't find the ref just now). But it didn't require amounts in the area of 6 - 10 grams sodium. Maybe you could enlighten me how much is required for those or for your condition. Salt of course can be used to raise BP - I've done that on occasion when over-medicated - so there's another special case. I'm not sure of the mechanism because the serum sodium normally doesn't change much. For dietary req'ts we have anything from 100 mg to 10 grams, depending on which source (and which era) you look at. U.S. is presently 2.4 grams and that should be the max (except for those marines), 1.5 grams for HTNer's. Exceptional cases requiring 1 qt of water per hour will excrete about 100mg x 32 oz or 3.2 grams of sodium per hour. I've not found how high their pressure goes with that intake and workload. If you look at hyponatremia or hypernatremia, the refs will say they are due to the kidney not controlling serum sodium. Electrolytes are controlled by the system. The body has as I recall about 350 grams of sodium in reserve if it wants to use it. There are also diseases that require a low sodium diet (Meniere's disease,eg). There is Sodium Wasting - usually a transient condition just preceding the development of end-stage renal disease. Clinical Syndrome of Inappropriate Antidiuretic Hormone (SIADH) is associated with a number of problems. But I think this group is not about diagnosing sodium problems or recommending solutions for disease. I assume your friends with low sodium problems are talking to their dr. Also I find it a little perturbing when general rec's of 5 to 10 glasses of water pd, are suggested, because there are probably many who don't need to drink that much. My cardio says drink when you're thirsty - that implies a fluid rate a heart can handle. I remember 5 glasses as a max number for CHF. I drink on average 5 pints per day, not counting any fluid from foods and I find that a limiting factor extending excretion to later in the evening. You might need more to support your extra sweating.

One M.D. told me: " if you're thin (I was) and have low BP, you'll > live forever " ........ : She is right: When I was 22 working in São o, eating all kinds of junkfoods: Macs, chocolate cakes, etc. My BP was (!!) 80/50. Hahhaha... My phisician told me to gain a few kilos (pounds). That time I was 132 pounds. I asked him about caloric restriction and he said (!!) you are too young to think about this! But I didn't folow him. I drop down my caloric intake, at that time and (surprise!) my BP increased to 120/80 and then drop solowly to 10/60 again, now it is 80/50 again. What the explanation? I don't know. Perhaps an adapation to stress hormones that are higer in a CR organism. So don't think that everything is " all right " because you eat ad-lib and your BP is low ................ AGING IS A SILENT ENEMY, like high blood preassure........... -- GAndhi. Quote Link to comment Share on other sites More sharing options...
